PTBnews 3.2018 – PTB is developing a measuring system based on pulse-driven Josephson voltage standards. This system is designed to allow alternating voltages to be measured with great accuracy at frequencies of up to 100 kHz and voltages of more than 100 V. Since the output voltages of Josephson voltage standards are limited to a few volts, it is necessary to use voltage dividers. An inductive voltage divider has now been calibrated for the first time with pulse-driven Josephson voltage standards, and the results have been compared to those obtained using a conventional calibration procedure.
